If you’re shopping for an air purifier, you’ll likely encounter ionic air purifiers. These work differently than the ones with high-efficiency particulate air (HEPA) filters, which have sort of become the “standard” air purifier. So are ionic air purifiers better?
What Is an Ionic Air Purifier?
Ionic air purifiers are air cleaners that help your remove or reduce ultrafine contaminants from the surrounding air. Also called ionizers or ion generators, the ionic air purifiers release a negative ion charge that attaches to the pollutants in the air and leads them to stick to a nearby surface. Some ionic air purifiers also come with a positively charged collector to attract the negatively charged pollutants.
Although ionic air purifiers are typically standalone units, some manufacturers have also started including air ionizers as a part of standard air purifiers with a HEPA filter. In such an air purifier, the air ionizer function is optional, and you can choose to switch it on or keep it off.
